yoko SAIGO: After the nuclear power plant in Fukushima had hydrogen explosion, the land, the water and air include great amount of cesium. There is black fungus funded in Chernobyl which absorb cesium instead of carbon. The architecture device provides the certain condition to cultivate the relationship between fungus and cesium in the site of the nuclear power plant in Fukushima. This project proposes a cultivation device that produces an environmental condition by understanding the potential for localized ecosystems.
